My W is the same. Pulled away from me and our S2 and continues to put her own needs well above his. She gave up one of her limited days with our S2 just because she wanted to hang out with her "friends" in the city. Likely she's having an affair and everything to do with our family just gets in the way of that life for her.
Priorities are obviously out of whack. Who knows why and better not to even try to figure it out.
